TANNERS PADDLE WHEEL.

Specification of Letters Patent.

Patented Oct. 10, 1905.

Application filed September 30, 1904. Serial No. 226,725.

To (LU who/rt it 7111.13, come/'7' Be it known that 1, EPIIRAIM L. BA'IEMAN, a citizen of the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Tanners Paddle-"heels; and ldo hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to numerals of reference marked thereon, which form a part of this specification.

This invention relates more particularly to that class of paddle-wheels which are employed by tanners to thoroughly agitate the liquors and stir the hides in the vats; and the objects of the invention are to provide such a paddle-wheel which can be cheaply and easily manufactured, to facilitate repairing or renewal of the wheel, to secure greater durability, to enable individual wheels of a series to be readily controlled independent of the others, and to obtain other advantages and results, some of which may be hereinafter referred to in connection with the description of the working parts.

The invention consists in the improved tanners paddle-wheel and in the arrangements and combinations of parts of the same, all substantially as will be hereinafter set forth and finally embraced in the clauses of the claim.

Referring to the accompanying drawings, in which like numerals of reference indicate corresponding parts in each of the several figures, Figure 1 is a cross-sectional view of my improved paddle-wheel, taken on line w, Fig. 2, and looking in the direction of the arrow. Fig. 2 is a longitudinal section, as on line 1 Fig. 1; and Fig. 3 is a detail section on line .2, Fig. 1.

in said drawings, 2 indicates a shaft which may be of any suitable length, extending through a number or series of tanks or vats, such as are common in tanneries, and upon which shaft are mounted a series of paddlewheels of my improved construction, each bolted together by overlapping flanges 6 6,

the said hub providing a central perforation or bearing 7 for the shaft 2. At its periphery each hub has a series of tongues 8, projecting radially and each of which is adapted to receive tlatwise against its side a spoke 9, the spoke being bolted, as at 10 10, to said arm 8 and stayed at its edges by means of terminal lugs 11 11 upon the said arm, and other lugs 12 upon the hub at the base of said arms. The said spokes are at their outer ends recessed at one edge, as at 13, to receive the paddles 1, and at their outer sides the end pieces or disks 3 are provided at the outer ends of their spokes 9 with annular guards 11, extending around the paddles at their ends. By the construction thus described it will be understood that if a paddle breaks the same is easily removed and replaced by another, and, furthermore, if a spoke in one of the end pieces or disks 3 should become broken it can be replaced by a new one without disassembling the entire wheel. Furthermore,

the construction is very simple, easy of manu-' facture, and conducive to economy.

For locking the paddle-wheel upon its shaft 2 to rotate therewith l have provided means comprising clamping-pieces 15 15, lying on opposite sides of the shaft and adapted to be clamped rigidly thereupon, as by bolts 16. Each of said clamping-pieces 15 provides at one of its ends a rad ially-projecting shoulder 17, and said pieces are clamped upon the shaft in such position that one lies at the inner side of each end piece or disk 3 of the paddlewheel. Upon an outer point of each disk 3 and at its side adjacent to said clam ping-pieces 15 15 is mounted a pair of dogs 18 18, each having a projection 19, adapted to engage the shoulder 1'7 of one of the pieces 15. It will be understood that when said dogs are in engagement with said pieces 15 the paddle-wheel will turn with the shaft and that when detached therefrom the paddle wheel will stand still. For releasing said dogs 18 to permit the paddle-wheel to stand idle connecting-rods 2O 20 extend from the dogs of each pair on the end disks 3, which are at one side of the driving-shaft 2, to levers 21 .21, pivoted, as at upon one of the blades or paddles 1 of the wheel. \Vhen it is desired to have the wheel rotate, said levers 21 21 are permitted to stand obliquely with respect to the blade or with their adjacent ends swung outward, as shown in full lines in Fig. 2; but if the wheel is to be idle said levers 21 9.1 are pressed downward or inward at their adjacent ends and locked in such position by means of a catch 23, as shoWn in outline in Fig. 2. This raises or lifts the dogs 18 18 out of engagement with the shoulders 17 17, so that the paddle-Wheel is loose upon the shaft 2 and remains idle.

A particular advantage of the construction thus described is that the means for controlling the paddle-Wheel or for throwing it into or out of engagement With the shaft are easily accessible from the peripheral exterior of the paddle-Wheel, and thus the Wheels are conveniently and positively under the control of the operator. Any particular one can be stopped or started independent of the others and Without interfering With the action of said other Wheels, and thus the hides and liquids in the vats can be agitated and brought into intimate relation as desired.

Preferably, to avoid excessive strain upon the dogs 18, I form upon the sections 5 of the hub integral stops or rests 2 1, against Which the dogs lie under the pressure of the clamping-pieces of the driving-shaft 2. These stops 24 therefore take the pressure in turning the paddle-Wheel and relieve the pivotal pins 25 of the dogs.

Having thus described the invention, What I claim as new is 1. A tanners paddle-Wheel, comprising opposite end pieces or disks each composed of a hub having semicircular sections adapted to be bolted together upon a shaft, spokes bolted to said hub and being each removable inclependent of adjacent spokes, paddles mounted upon the outer ends of said spokes, and means for locking the paddle-Wheel to the shaft to turn therewith or releasing the same to stand idle.

2. A tanners paddle-Wheel, comprising end pieces or disks adapted to be mounted on a shaft and each having a hub composed of sections adapted to be bolted together, said hub having radial arms providing lateral spokeseats independent of one another, spokes mounted in said seats of the hub, paddles upon the outer ends of said spokes, and means for locking said end pieces or disks to a shaft or disconnecting them therefrom.

3. A tanners paddle-Wheel comprising end pieces or disks each composed of sectional hubs having radially-projecting arms With lateral lugs at the side edges of said arms, spokes bolted to said arms between said lugs, paddles mounted on the outer end of said spokes, annular rings upon said spokes at the ends of said paddles, and means for locking said end disks to ashaft or disconnecting them therefrom.

4. The combination With the shaft and radially-projecting clamping-pieces thereon, of a tanners paddle-Wheel having opposite end pieces or disks and paddles mounted upon said disks, dogs upon the end disks adapted to engage said clamping-pieces upon the shaft, levers pivoted upon one of said paddles and connecting-rods extending from said levers to said dogs to operate the same.

5. The combination With the driving-shaft and radial projections 17, thereon, of a paddle-Wheel having opposite end pieces or disks, dogs upon said end pieces adapted to engage said projections of the shaft, fixed stops upon the disks to receive the dogs as they are pressed by the projections, and means for throwing said dogs into and out of engagement.

In testimony that I claim the foregoing 1 have hereunto set my hand this 10th day of September, 1904.
